Application filed April 19, 1919. Serial No. 291,367;

(FILED UNDER THE ACT 01 MARCH 3, less, 22 smart. L, 625.)

To all whom it may concern:

Be it known that I, JOHN S. BUTLER, Capt, Ordnance Dept, U. S. Army, a citizen of the United States, stationed at Washington, D. 0., have invented an Improvement in Detachable Stocks for Firearms, of which the following is a specification.

The invention described herein mayv be used by the Government, or any of its officers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

The subject of this invention is a detachable stock for firearms adapted, primarily, for use on machine guns.

The main object of the invention is the provision of astock which may be readily attached to a gun when it is desirable to use a stock with the gun.

Another object of the invention is the provision of means for securely binding the stock in place on the gun.

The invention also contemplates providing a simple, cheap and efiicient gun stock;

With the foregoing and other objects in view, the invention residesin the combination and arrangement of parts and 1n the details of construction hereinafter-described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made withthe scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawing, wherein Figure 1 is a side elevation of a machine gun showing a stock, constructed in accord ance with the invention, in place thereon; and

Fig. 2 is anend view ofthe stock, remote parts removed.

Referring to the drawing by numerals of A usual form of machine gun is illustrated, consisting of arecoil casing,1, from which the barrel, 2, projects forwardly, and

an extension, 3, projects rearwardly of said casing, being provided with the usual de pending grip, 4.

Upon the extension,-3, is secured a stock, which formsthe subject of the present .in-' vention, said stock consisting of a tubular shank, 5, connected to an arcuate shoulder rest, 6, at its rearmost end, and split for a short distance longitudinally, as indicated at 7, Fig. 2, to straddle the grip, i, and per- Epecification of Letters Patent. Pat ted J 21, 1921 r mit of proper placement upon the extension,

3. The tubular shank, 5, is 'bound or clamped on the extension, 3, by means of a split collar, 8, or like clamping member which surrounds the-tube at its forward end,

and which is clamped about the tube by any suitable means, such as is herein shown, wherein one end of the collar, 8, is bent'or rolled to form an eye, 9, adapted for link enupon itself to form a loop, 11, which is' apertured, as at 12, to receive the threaded end of the eye-bolt.

A wing-nut, or like element, is

the ends of the collar toward each other and so clamp the tubular member upon the ex tension" to detachably V secure the stock in place. I

It is thought thatthe operation of the device can be amply understood from'the foregoing description without a specific and extended explanation thereof. 7

Having described my invention, what I claim as new and desire to secure'by Letters .Patent, is

l. A gun stock, including a tubular shank gagement with the eye of an eye-bolt, 10, while the other end of the collar is bent Y V threaded on the end of theeye-bolt and serves to'draw split Y longitudinally for a portion of its length, a shoulder rest secured to the shank,

and-means encircling the shank for binding the stock in place upon'the gun.

2. A gun stock, including a tubular shank split longitudinally for a portion. of its a collar encircling the split end of the shank, and means for compressing the collar to bind'the shank in place upon the gun.
